References to Inaccessible or Missing Items

When you open an existing analysis, it may reference items from the underlying data source that are missing or inaccessible. This may occur for one of these reasons:

The model changed.
For example, a level may no longer be present, or an item that previously existed is no longer present after refreshing the data source.
Part of the data source, such as an item, level, hierarchy, or dimension, is inaccessible because of security restrictions.

When this occurs, a dialog box prompts you to either replace the missing items, or have IBM® Cognos® Analysis Studio prune the analysis by removing inaccessible items and their dependent items, such as filters, calculations, sorts, and so on.

For example, an analysis contains revenues for three countries or regions plus a calculated column and a filter. If the item for one of the countries or regions is missing and you choose to prune the analysis, Analysis Studio will remove the calculation and the filter and show the analysis without the missing item.
